説明
<jats:p> <jats:bold> Pressureless sintering was used to densify ZrB <jats:sub>2</jats:sub> –SiC ultra‐high temperature ceramics. The physical, mechanical, thermal, electrical, and high temperature properties were investigated. This comprehensive set of properties was measured for ZrB <jats:sub>2</jats:sub> containing 20 vol% SiC in which B <jats:sub>4</jats:sub> C and C were used as the sintering aids. The three‐point flexural strength was 361±44 MPa and the elastic modulus was 374±25 GPa. The Vickers hardness and fracture toughness were 14.7±0.2 GPa and 4.0±0.5 MPa·m <jats:sup>1/2</jats:sup> respectively. Scanning electron microscopy studies of the microstructure of ZrB <jats:sub>2</jats:sub> –SiC showed that SiC particles were distributed homogenously in the ZrB <jats:sub>2</jats:sub> matrix with little residual porosity. </jats:bold> </jats:p>
